HOLLYWOOD star Mila Kunis has been named FHM's Sexiest Woman in the World for 2013.

The 29-year-old actress, who ic currently dating Ashton Kutcher, has knocked N-Dubz star Tulisa Contostavlos off of the top spot.

Mila’s victory brings to an end a four-year run of British winners, but no doubt fans will be pleased as Tulisa's 2012 win came as quite a shock.

"Mila Kunis has had a phenomenal year – she’s starred in the highest grossing comedy (Ted) and is the most in-demand Hollywood star right now," said FHM 100 Sexiest Editor Dan Jude.

The actress has been described as "naturally stunning" following her triumph (WENN)

"Not only is she naturally stunning, but she has a great sense of humour and isn’t afraid to poke fun at herself. The nation has spoken, and the verdict is that she is officially the perfect girlfriend. She’ll take some beating in 2014."

Unfortunately, Tulisa doesn't even find herself in the top ten this year but there is a new face in the form of 'The Big Bang Theory' star Kaley Cuoco, who came in at number six.

Close behind Mila is worldwide superstar Rihanna, who has moved up one place from last year.
